Knee arthritis
The word arthritis refers to inflammation of the joints.[3][4] Types of arthritis include those related to wear and tear of cartilage, such as osteoarthritis, to those associated with inflammation resulting from an overactive immune system (such as rheumatoid arthritis).[5][6]
Diagnosis[edit]
Osteoarthritis of the knee[edit]
Diagnosis of knee osteoarthritis often entails a physical examination, assessment of symptoms and the patient's medical history, but may also involve medical imaging and blood tests.[1] Persistent knee pain, limited morning stiffness and reduced function, crepitus, restricted movement, and bony enlargement appear to be the most useful indications of knee osteoarthritis for diagnosis.[17]
Standardized medical questionnaires like the Knee injury and Osteoarthritis Outcome Score (KOOS)[18] and short form KOOS JR.[19] or the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)[20] can also be used to diagnose and monitor progression of knee osteoarthritis.
